As said in the title, there are time I can't explain why, but it goes through the whole export, but the output video is juste ~1 to 2seconds long ending abruptly.
The export process goes through all the frames.
And looking at the developer console does not show any warning or error, so I'm not sure what's happening there.
I'm using it on Mac OS X (10.15.7) and it is the last version, at least the check update says so (version 1.2.0) I haven't try to build a version from the sources yet, but most of the changes has been package updates, so I doubt it would fix anything.
